Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings.

It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present application belongs. The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

As described in the background section, the virtual scene is a virtual space for the player to play the game, and the game developer can make a game scene in advance in the development stage, and load the prefabricated scene for the player to experience when the player plays the actual game.

As a result of the study by the inventors, it was found that, in the related art, when a very large virtual scene, for example, a scene having a scene size of (1000×1000) meters is created, the entire scene can be photographed when a virtual camera in the scene is located at a high altitude of 3000 meters to take an overhead. Then, in the process of editing such huge virtual scenes, the related art needs to load the entire scene, enlarge a part of the scene, edit the scene by screen, and even cause serious engine jam due to excessive scene loading resources. In such a scene editing mode, the cost of resources and time used is high, and the step of scene editing can only satisfy single-person single-thread operation, and the engine file can only be maintained by one game developer, so that the virtual scene needs to be produced at a great deal of cost and with a long production period.

And various bug frequently appear in very large-scale scene and are difficult to test, and the setting workload of a blanking model is huge and is extremely easy to make mistakes in operation, and once a certain area in the virtual scene has a bug, the specific bug position is difficult to accurately check out.

According to the research of the inventor, in another related technology, referring to fig. 1, a scene can be automatically generated by using Houdini (a three-dimensional computer graphic software), the splicing principle is that the basic topography is fluctuated and the connecting layer is mostly adopted, the scene is modified with little landscape, and the finally realized scene is still very empty. If rich picture content is desired, a modular model with multiple added is required. Because the land palace scene class checkpoint route is mostly horizontal and vertical, and the route topography area is even, the scene that the automation produced is relatively dead in most cases. The scene route lacks change, the scene inside lacks the theme design, lacks atmosphere change, can not reach the step-by-step and trade the scene effect.

Therefore, the virtual scene construction method, the virtual scene construction device, the electronic equipment and the storage medium are used for splicing the plurality of scene module plane diagrams according to the unit pixel modules acquired in advance; performing 3D (three-dimensional) operation on the scene module plan according to scene information in the scene module plan so as to construct a plurality of scene modules corresponding to a plurality of scene module plan; wherein, each scene module at least comprises: a path; determining path information corresponding to the paths in each scene module; and acquiring scene demand parameters, and splicing the scene modules corresponding to the path information according to the scene demand parameters to construct a target virtual scene. According to the method and the device, the scene module plan is obtained through unit pixel module splicing, and compared with the scene design changing in a 3D scene, the scene module plan can be changed rapidly. And the target virtual scene is divided into a plurality of scene modules to be edited respectively, so that the editing cost is reduced, and each scene module can be edited respectively by a plurality of developers, so that the editing period is shortened to a certain extent. Further, by splicing different scene modules, a complete target virtual scene is obtained, and because the scene modules spliced with each other can be freely selected in the splicing process, the generation effect of the whole target virtual scene is more diversified, different target virtual scenes can be spliced through a plurality of different scene modules in the same group, and the virtual scenes are richer and more diversified.

Referring to fig. 2, in this application scenario, a local terminal device 101 and a server 102 are included. The local terminal device 101 and the server 102 may be connected through a wired or wireless communication network, so as to implement data interaction.

In some exemplary embodiments, the virtual scene construction method may be run on the local terminal device 101 or the server 102.

The server 102 splices a plurality of scene module plane diagrams according to the pre-acquired unit pixel modules; performing 3D (three-dimensional) operation on the scene module plan according to scene information in the scene module plan so as to construct a plurality of scene modules corresponding to a plurality of scene module plan; wherein, each scene module at least comprises: a path; determining path information corresponding to the paths in each scene module; and acquiring scene demand parameters, and splicing the scene modules corresponding to the path information according to the scene demand parameters to construct a target virtual scene. The server 102 may also send the target virtual scene to a client, which exposes the target virtual scene to the user. Wherein the terminal device may be the aforementioned local terminal device 101.

When the virtual scene construction method is run on the server 102, the method can be implemented and executed based on a cloud interaction system.

The cloud interaction system comprises a client device and a cloud game server.

In some example embodiments, various cloud applications may be run under the cloud interaction system, such as: and (5) cloud game. Taking cloud game as an example, cloud game refers to a game mode based on cloud computing. In the running mode of the cloud game, the running main body of the game program and the game picture presentation main body are separated, the storage and running of the control method of the moving state in the game are completed on the cloud game server, and the client device is used for receiving and sending data and presenting the game picture, for example, the client device can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; but the cloud game server which performs information processing is a cloud. When playing the game, the player operates the client device to send an operation instruction to the cloud game server, the cloud game server runs the game according to the operation instruction, codes and compresses data such as game pictures and the like, returns the data to the client device through a network, and finally decodes the data through the client device and outputs the game pictures.

In the above embodiments, the description has been given taking an example in which the virtual scene construction method is run on the server 102, but the present disclosure is not limited thereto, and in some exemplary embodiments, the virtual scene construction method may also be run on the local terminal device 101.

For example, the local terminal device 101 may include a display screen for presenting a graphical user interface including game visuals, and a processor for running the game, generating the graphical user interface, and controlling the display of the graphical user interface on the display screen.

In some exemplary embodiments, the embodiments of the present disclosure provide a virtual scene construction method, where a graphical user interface is provided through a terminal device, where the terminal device may be the aforementioned local terminal device 101 or may be a client device in the aforementioned cloud interaction system.

The virtual scene construction method according to an exemplary embodiment of the present disclosure is described below in connection with the application scene of fig. 2. It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principles of the present disclosure, and the embodiments of the present disclosure are not limited in any way in this respect. Rather, embodiments of the present disclosure may be applied to any scenario where applicable.

Referring to fig. 3, the method for constructing a virtual scene provided in the embodiment of the present application specifically includes the following steps:

s302: and splicing a plurality of scene module plane diagrams according to the pre-acquired unit pixel modules.

S304: performing 3D (three-dimensional) operation on the scene module plan according to scene information in the scene module plan so as to construct a plurality of scene modules corresponding to a plurality of scene module plan; wherein, each scene module at least comprises: a path.

S306: and determining path information corresponding to the paths in each scene module.

S308: and acquiring scene demand parameters, and splicing the scene modules corresponding to the path information according to the scene demand parameters to construct a target virtual scene.

When a virtual game scene, such as an ultra-large underground city scene, is manufactured, first, a world view, a story prototype, a main character biography, an environment region, a time period, a map area, and a part of special needs in the scene need to be set. Then, in the construction work of ase:Sub>A specific virtual game scene, one of the key points in the application is to divide ase:Sub>A huge virtual scene into ase:Sub>A plurality of modules, splice the plurality of modules in ase:Sub>A mode of 'jigsaw', and further splice ase:Sub>A complete virtual scene, so that time and labor are obviously saved, the splicing mode is not unique, the construction effect of the whole virtual scene is enriched, for example, A, B, C modules are provided, splicing into ase:Sub>A straight shape, for example, A-B-C or B-A-C can be selected on the premise of meeting the splicing requirement and the splicing rule, and the virtual scene can be spliced into other shapes such as an L shape, which is the benefit brought by ase:Sub>A modularized splicing process.

In some embodiments, the type of region that may occur in a scene may be determined based on world view, story prototype, primary character biography, environmental territories, time periods, map area, and some special needs, which may be custom set by a planner or game developer. Specifically, we can obtain in advance a unit pixel module such as in fig. 4, in which a plurality of regions distinguished by different colors, such as a birth region, a connection channel, a danger region, an escape region, a rich region, a hidden region, and a contended region, can be included. The unit pixel modules can be set to be square modules with the size of 50x50, and the unit pixel modules are convenient to splice.

Further, a virtual scene generally includes a path area for a player to walk, and a non-path area for placing environmental factors such as buildings, vegetation, and lakes, and the unit pixel module may include a first type of pixels and a second type of pixels. Wherein the first type of pixels may be represented by a plurality of unit pixel modules in a first row, for example, in fig. 4, for characterizing a path region, and the portion for characterizing a non-path region may be a second type of pixels, for example, represented by a plurality of unit pixel modules in a second row, for example, in fig. 4. The unit pixel modules shown in the third row may be obtained by disposing both in the same plan view, that is, the path region and the non-path region appear simultaneously in the plan view.

Specifically, the path area, the path position, the non-path area and the non-path position in the multiple scene module plan views can be determined according to the pre-acquired splicing requirement information, and then the first type pixels can be spliced at the path positions in the multiple initial plan views with preset sizes to obtain the path area corresponding to the path area. Further, stitching the second type of pixels at non-path positions in the plurality of initial plan views to obtain a non-path region corresponding to the non-path area, and determining a plurality of scene module plan views according to the path region and the non-path region.

The splicing requirement information may be used to indicate a path area, a path position, a non-path area, and a non-path position, for example, may be a plane image, splice each module in fig. 4 in the image, splice the modules corresponding to the path together to determine the path position, determine the path area according to the module area corresponding to the path, splice the modules corresponding to the non-path together to determine the non-path position, and determine the non-path area according to the module area corresponding to the non-path. In this way, the first type of pixels can be further spliced at the path position in the initial plan view with a preset size, for example 1000x1000, so as to obtain the path region, and the second type of pixels can be spliced at the non-path position, so as to obtain the non-path region, and further, the scene module plan view is obtained according to the path region and the non-path region.

That is, the stitching requirement may be used to characterize the required path region and non-path region in one or more scene module plan views, so that the path area, path position, non-path area, non-path position, etc. information in the scene module plan view may be determined. Further, in the initial plan views of the preset size, for example, in the initial plan view of 50×50 as shown in fig. 5, the positions corresponding to the "walkable region", "stair down", and "down-to-next-floor walkable region" in the initial plan views can be determined according to the path positions, so that the pixels of the first type are spliced to the path positions until the path regions corresponding to the path areas are obtained. Similarly, for the non-path area, the position corresponding to the non-path area may be determined according to the non-path position, for example, the position corresponding to the intersection for blocking the non-path and the non-walkable area may be included, and then the second type of pixels are spliced to the non-path position until the non-path area corresponding to the non-path area is obtained. Still further, a scene module plan may be determined based on the path region and the non-path region.

After the scene module plan is obtained, the scene module plan can be subjected to artistic processing in order to enable a game developer to construct a specific virtual scene through the scene module plan more intuitively. Drawing art processing can be performed on the scene module plan shown in fig. 5, for example, by using drawing software without changing the form and layout, so as to obtain a thinned scene module plan shown in fig. 6, for example.

In yet another implementation, a preset map may be obtained in advance, with which to give a plan view of the scene module as shown in fig. 5. For example, a path area may be given a first preset map obtained in advance, so as to obtain a path plan view, and a non-path area may be given a second preset map obtained in advance, so as to obtain a non-path plan view, and further, a refined scene module plan view, for example, as shown in fig. 6, may be determined according to the path plan view and the non-path plan view.

For a scene module plan, when splicing scene modules constructed from a plurality of different scene module plan, one of the main factors to be considered in practice is the interface of the path area on that side for splicing, similar to the shape of the splice location of the "puzzle", for example, the "male" can be spliced with the "female". In other words, if the positions and the number of intersections of the path regions are the same in the scene module plan, different path directions and contents of non-path regions can be set in the scene module plan to obtain different scene module plan, so that a plurality of scene module plan can be produced more quickly and conveniently. Referring to fig. 7 (a) - (c), there are shown plan views of three scene modules with different interior path trends and different contents of non-path regions, with the same intersection location and number.

After obtaining the scene module plan, a scene module for splicing the target virtual scene needs to be obtained, and an important step is to execute 3D operation on the scene module plan according to the scene information in the scene module plan so as to construct a plurality of scene modules corresponding to the plurality of scene module plans.

In some embodiments, the path plan view and the non-path plan view in each scene module plan view may be equally divided into a plurality of plane grids, and scene information corresponding to each plane grid may be determined, where the scene information may include at least: RGB values corresponding to the planar grid. Further, a height value for each planar mesh at a corresponding location in the scene module may be determined from the RGB values for each planar mesh, where the RGB values may be proportional or inversely proportional to the height values. For example, the sum of the square value of the R value, the square value of the G value, and the square value of the B value may be determined, and the sum may be root to determine a height value, that is, two different relationships may be represented between the RGB value and the height value, for example, one is that the larger the RGB value is, the larger the height value is, the overall trend approximates a positive proportional relationship, and the second is that the larger the RGB value is, the smaller the height value is, the overall trend approximates an inverse proportional relationship, and is not specifically limited herein.

Still further, according to the height value of the corresponding position of each planar grid in each scene module plan in the scene module, 3D transformation operation can be performed on each planar grid in each scene module plan, so as to construct a plurality of scene modules containing paths corresponding to the path plan.

Specifically, the 100x100 scene module plan can be divided into a plurality of 5x5 plane grids, so that the artistic effect in the scene module plan can be more flexibly represented, and the precision of the scene module plan can be better controlled. After obtaining the scene module plan, if the scene module obtained after the 3D operation is to be determined according to the information in the scene module plan, the height value of each position after the 3D operation needs to be determined to obtain a three-dimensional scene module. Then, the height of the position corresponding to the scene module may be determined according to the RGB value corresponding to the planar grid, for example, the RGB value corresponding to the planar grid may be proportional to the height value of the region corresponding to the planar grid in the scene module, that is, the larger the RGB value corresponding to the planar grid, the larger the height value of the region corresponding to the planar grid in the scene module. Of course, the RGB value corresponding to the planar grid may be inversely proportional to the height value of the area corresponding to the planar grid in the scene module, that is, the larger the RGB value corresponding to the planar grid is, the smaller the height value of the area corresponding to the planar grid in the scene module is.

Whether the RGB values and the height values are in a direct proportion relation or an inverse proportion relation, the height value of the corresponding position of each planar grid in the scene module can be determined according to the RGB values of the planar grids in the scene module plan, and then the planar grids can be subjected to 3D processing in 3D software, so that the scene module corresponding to the scene module plan is constructed. Of course, the height may be limited, e.g., the maximum height cannot exceed 20 units, which 20 units are defined by the bottom surface of the scene module along a vertical axis in the three-dimensional coordinate system, e.g., the center point coordinates of the bottom surface of the scene module may be (0, 0).

In some embodiments, an initial height value corresponding to the minimum RGB value may be set, for example, the initial height corresponding to the RGB value (0, 0) may be 0 units, and further, a difference between the RGB value corresponding to each planar grid and the minimum RGB value may be determined. If the difference between the RGB value corresponding to the planar grid and the minimum RGB value reaches a preset multiple of the preset interval RGB value, for example, one of the planar grids corresponds to RGB value (128, 128, 128), the preset interval RGB value is (64, 64, 64), and the preset multiple is 1, the height value of the corresponding position of the grid in the scene module may be increased by a preset height value, that is, if the initial height value of the corresponding position is 0 in the plane, the difference between the RGB value corresponding to the current planar grid and the minimum RGB value reaches 2 times the preset interval RGB value, for example, the preset height value may be increased by 2 preset height values, for example, 5 units, and in fact, the height value of the corresponding position of the planar grid in the scene module is changed from 0 to 10 units.

In other embodiments, an initial height value corresponding to the maximum RGB value may be set, for example, the initial height corresponding to the RGB value (256, 256, 256) may be 0 units, and further, a difference between the RGB value corresponding to each planar grid and the maximum RGB value may be determined. If the difference between the RGB value corresponding to the plane grid and the maximum RGB value reaches a preset multiple of the preset interval RGB value, for example, one of the plane grids corresponds to RGB value (128, 128, 128), the preset interval RGB value is (64, 64, 64), and the preset multiple is 1, the height value of the corresponding position of the grid in the scene module may be increased by a preset height value, that is, if the initial height value of the corresponding position is 0 in the plane, the difference between the RGB value corresponding to the current plane grid and the maximum RGB value reaches 2 times of the preset interval RGB value, 2 preset height values may be increased, for example, the preset height value is 5 units, and in fact, the height value of the corresponding position of the plane grid in the scene module is changed from 0 to 10 units.

In some embodiments, the center position of the scene module plan may also be determined, and the corresponding position of the planar grid in the scene module, which is more than a preset distance from the center position, is determined as a boundary, for example, the overall scene module size is 1000x1000, and then the position with a distance of 500 from the center position is defined as the boundary. Further, the corresponding position of the planar mesh in the path plan in the scene module may be determined as a path, i.e. the planar mesh in the path plan corresponds to the path. The RGB value of the plane grid corresponding to the first area containing the path in the boundary is set as the first RGB value, and the RGB value of the plane grid corresponding to the second area not containing the path in the boundary is set as the second RGB value, namely the path area and the non-path area are represented by different RGB values, and the path area and the non-path area are distinguished. Still further, a first height value corresponding to the first area may be determined according to a first RGB value of the planar grid corresponding to the first area, and a second height value corresponding to the second area may be determined according to a second RGB value of the planar grid corresponding to the second area. And the height value of the first area containing the path and the second area not containing the path area can be determined directly according to the first RGB value and the second RGB value.

In some embodiments, for 3D rendering of the scene module plan, a white-box model block of a unit volume may be sequentially placed at each corresponding position of the planar grid in each scene module plan according to the height value of each corresponding position of the planar grid in each scene module plan in the scene module plan, so as to construct a white-box scene module, for example, referring to fig. 8, a white-box scene module corresponding to the scene module plan shown in fig. 6 is shown.

The 3D operation is to make the 2D plan as a 3D model, for example, a white-box scene module is obtained according to the scene module plan, where the white-box scene module is a 3D model. For example, it can be implemented in 3D software by means of a simple patch and a simple white-box model block (for example, made in the form of cubes of 5m or 10m or 1 m). And then in an engine (such as a UE4 engine), the wall model and the ground surface sheet are subjected to 3D route implementation around the route according to a route map. The heights of the walls are regular, for example, the heights of the walls can be 5 meters and 10 meters, and the walls can be spliced up and down according to the topography requirement to form the walls with different heights, which also accords with the theory of building floors.

The software for performing 3D rendering operations, which may be, for example, a 3D Maker, may convert a 2D planar image into a 3D model, be compatible with JPG, BMP, PNG, GIF, etc. in various picture formats, support various 3D effect selections, such as spherical, cylindrical, conical, etc. High-precision 3D models can also be generated by inputting depth images and texture images using, for example, depthmap x software. DepthmapX supports a variety of depth image input modes including triangulation, laser scanning, stereography, and the like. For another example, blender software may be used to support not only 3D modeling, animation, etc., but also the conversion of 2D planar images into 3D models. Blender provides a variety of 3D conversion tools, and a user can select different tools according to own needs.

Further, pre-acquired virtual assets, such as the various types of virtual assets shown in fig. 9, may be bound at preset locations in the white-box scene module, and the white-box scene module may be beautified by using the virtual assets to construct the scene module shown in fig. 10.

Still further, light, path finding and blocking can be made, and finally all objects, light, path finding and blocking binding are grouped together by using a function of preserving model groups of Neox2 software, so as to obtain a scene module which is more close to the setting of the target virtual scene.

It should be noted that, in practice, the height values of different regions corresponding to the 3D scene module may also be marked in the scene module plan, for example, a first height parameter indicating the height value of the path region corresponding to the position in the scene module in the path plan may be read, and a second height parameter indicating the height value of the non-path region corresponding to the position in the scene module in the non-path plan may be read, that is, the height value corresponding to each grid is marked in advance in the path plan and the non-path plan. Further, a 3D operation may be performed on the path plan view according to the first height parameter, and a 3D operation may be performed on the non-path plan view according to the second height parameter, to construct a plurality of scene modules corresponding to the plurality of scene module plan views. In addition, light rays, fog effect, flame, smoke and height can be designed in the 3D engine, and a simple plane checkpoint is perfectly 3D.

Regardless of the manner in which the 3D scene module is obtained, some rules need to be complied with to ensure the rationality of the scene module, for example, it may be determined whether the angle between the plane on which the path is located and the bottom surface of the scene module exceeds a preset angle, for example, the preset angle may be set to 45 °. If the included angle between the plane where the path is located and the bottom surface of the scene module exceeds the preset angle, the height value corresponding to the path can be adjusted so that the included angle between the plane where the path is located and the bottom surface of the scene module is smaller than or equal to the preset angle, and the RGB value of the plane grid corresponding to the path in the scene module plan view is redetermined according to the adjusted height value corresponding to the path. That is, it may be determined whether the gradient of the path in the scene module is too large, for example, the preset angle may be 45 °, and once the gradient of the path exceeds 45 °, the scene module may look abrupt, and in practical applications, the player may feel that the virtual character walks in the target virtual scene unnatural when playing in the target virtual scene. Further, the height value of the path with the gradient exceeding 45 ° is adjusted, and the path is further smoothed until the gradient is less than or equal to 45 °, and the RGB value of the planar grid corresponding to the path with the adjusted height value is required to be adjusted accordingly in the scene module plan view.

When splicing is carried out subsequently, for any one of the scene modules, an intersection used for communicating with paths in other scene modules can be determined according to the extending direction of the paths in the scene module, and intersection position information, intersection quantity information, intersection size and intersection opening direction corresponding to the intersection are determined. Further, path information corresponding to the path in each scene module can be determined according to intersection position information, intersection quantity information, intersection size and intersection opening direction corresponding to the intersection in each scene module. For example, one scene module includes 1 intersection in one of the sides a, the side B includes 2 intersections, the side C includes 0 intersections, and the side D includes 1 intersection, and then intersection position information may be represented as different sides including intersections. The intersection quantity information is 1, 2, 0 and 1. The size of the intersection can be determined according to the distance between two sides of the intersection in the scene module, and the opening direction of the intersection is the direction corresponding to each side, namely the direction of the intersection. Referring to fig. 11, it can be seen that when all scene modules are spliced, a plan view is used to show the spliced scene, so that a plurality of paths which are mutually communicated can be obtained.

Specifically, the required number of the scene modules can be determined according to the scene requirement parameters, and for any one of the scene modules, the intersection number information and the intersection size of any one side of the scene module can be the same, and other scene modules corresponding to the intersection position information and the intersection opening direction of the scene module are spliced with the scene module, so that the included angle of the planes of the two paths of the splicing position between the scene modules is in a preset angle interval, and the paths are mutually communicated. Further, all paths in the scene modules can be connected by splicing the scene modules, and the number of the scene modules subjected to splicing reaches the required number of the scene modules so as to construct and obtain the target virtual scene. Referring to fig. 12, the white-box scene module of the spliced target virtual scene before decoration is set corresponds to the plan view in fig. 11, that is, each path is mutually communicated.

In some embodiments, it may be determined whether there are candidate scene modules in which the number of intersections information and the size of the intersections on the first side are the same as the number of intersections information and the size of the intersections on the second side in the scene modules in other scene modules, where the number of intersections information on each side is greater than the preset number. If the number of intersections is larger than the preset number, candidate scene modules with the same number of intersections and the same intersection size as the number of intersections and the same size of intersections on the second side in the scene modules exist in other scene modules, whether the candidate scene modules have target scene modules with the directions of openings of the intersections on the first side opposite to the directions of openings of the intersections on the second side in the scene modules and the intersection position information on the first side overlapped with the intersection position on the second side in the scene modules is determined. If a target scene module exists in the candidate scene module, wherein the direction of the intersection opening of the first side is opposite to the direction of the intersection opening of the second side in the scene module, and the intersection position information of the first side is overlapped with the intersection position of the second side in the scene module, the second side of the scene module and the first side of the target scene module can be spliced with each other to obtain a path communicated with each other between the scene modules.

For example, the scene module 1 has an intersection M with an intersection size of 10 toward the first direction (e.g., the left direction), and the intersection M is located at the very center of the edge a, that is, the intersection M is located at the same distance from both ends of the edge a. The scene module 2 has an intersection N with an intersection size of 10 toward the second direction, and the intersection N is located at the very center of the edge B, that is, the intersection N is the same distance from both ends of the edge B, and the second direction is opposite to the first direction, for example, the right direction. The number information of the intersections in the side a of the scene module 1 and the side B of the scene module 2 are the same as the size of the intersections, and the intersection position information of the intersections M and N are opposite to the opening direction of the intersections, so that the side a of the scene module 1 and the side B of the scene module 2 can be spliced, and the paths which are communicated with each other and are in the preset angle interval are obtained by the included angle of the planes of the two paths of the splicing position between the scene module 1 and the scene module 2.

In other embodiments, if the intersection number information of the first side and the intersection number information of the second side are zero, the second side of the scene module is stitched to the first side of any one of the candidate scene modules. That is, if two of the scene modules respectively have a number of intersections of 0 in one side, that is, no intersections are included, the two sides of the two scene modules can be spliced.

If there is no target scene module in the candidate scene module in which the direction of the intersection opening of the first side is opposite to the direction of the intersection opening of the second side in the scene module and/or the intersection position information of the first side overlaps with the intersection position of the second side in the scene module, determining whether there is a target scene module in the candidate scene module in which the direction of the intersection opening of the first side is opposite to the direction of the intersection opening of the second side in the scene module after the transformation operation, and the intersection position information of the first side overlaps with the intersection position of the second side in the scene module, wherein the transformation operation at least includes: and rotating operation with a central axis which is perpendicular to the bottom surface of the scene module and passes through the center point of the scene module as a rotating axis. If a target scene module, in which the intersection opening direction of the first side is opposite to the intersection opening direction of the second side in the scene module after the transformation operation, exists in the candidate scene module, and the intersection position information of the first side is overlapped with the intersection position of the second side in the scene module, the second side of the scene module and the first side of the target scene module are spliced with each other, so that a path which is communicated with each other between the scene modules is obtained.

For example, the scene module includes four sides in the up-down, left-right directions, and then the upper side of the scene module 1 has an intersection K, and the intersection K is located at the very center of the upper side, and the right side of the scene module 2 has an intersection L, and the intersection L is located at the very center of the right side. Then, at this time, the scene module 2 is rotated by 90 ° counterclockwise about the central axis perpendicular to the bottom surface of the scene module 2 and the central point of the scene module 2, and then the direction of the intersection L is changed from the right direction to the downward direction, and at this time, after the edges corresponding to the intersection K and the intersection L are spliced, the scene module 1 and the scene module 2 can be spliced.

In some embodiments, the heights of the paths may not be uniform in the same scene module, i.e., the paths in one scene module have a gradient, which, of course, also needs to be less than or equal to a predetermined angle, such as 45 °. Then, when two scene modules meeting the splicing conditions in the foregoing embodiments are spliced, it is also necessary to consider whether the extension of the spliced path meets a certain requirement. Specifically, when the gradient exists in the paths of the intersections where the two scene modules are spliced, the extending directions of the planes of the paths of the two adjacent module intersections and the ground are complementary, so that the smoothness and smoothness of the paths can be ensured after the two paths are spliced.

It should be noted that if there is an angle between the paths that need to be spliced by the two scene modules, for example, both paths are ascending or both paths are descending, a V-shaped path is presented after the splicing, or an inverted V-shaped path is presented, and as long as the gradient is less than or equal to a preset angle, for example, 45 °, the paths are considered to be capable of being spliced.

In some embodiments, for the overall scene stitching, the technician may have special requirements, such as a wide room in the scene after several adjacent scene modules are stitched, and then it is necessary to ensure that the maximum width of the road in the corresponding module reaches a predetermined width, such as the narrowest of the road is no less than 15, and the widest is no more than 90. And the road area reaches the preset area, the minimum is not less than 15x15, and the maximum is not more than 90x90.

In the whole scene obtained by splicing, the utilization rate of the module can be determined according to the number of intersections of one module, for example, the multiplexing rate is high if the number of intersections is large. The usage rate is low when the number of intersections is reduced. The maximum number of the intersections is not more than 8, the number of the intersections is not less than 1, and the modules with the reduced number of the intersections are regarded as custom modules. And determining the weight of the module according to the utilization rate, wherein the more the number of the intersections is, the higher the weight is, and the less the number of the intersections is, the lower the weight is. The general module must guarantee to be 8 crossing, and the module quantity ratio of general module must be high just can let scene circuit show abundantly. At the same time, a certain amount of custom modules with few intersections must be present to make the route more interesting.

After the target virtual scene is constructed, the target virtual scene can be tested to ensure the rationality of the path of the target virtual scene so as to avoid program loopholes when the target virtual scene is formally put into use. For example, a path-finding track distributed along the path may be generated according to the path in the target virtual scene, and further, it may be determined whether there are at least two path-finding tracks that are not communicated with each other. If at least two non-communicated path-finding tracks exist, replacing a scene module corresponding to the path-finding track with shorter length until at least two non-communicated path-finding tracks do not exist in the target virtual scene. And further, each path of the finally obtained target virtual scene is communicated, and the phenomenon that the non-communicated path cannot be used is avoided.

Referring to fig. 13, it can be seen that after stitching and after finishing the beautification and decoration, the paths presented are communicated and that inside the target virtual scene, the paths are sloped, for example, the stepped portions are presented at an upward slope angle.

The running test software can also be used for carrying out actual running test on the target virtual scene, and in particular, a plurality of collision bodies can be arranged on the path-finding track, wherein the collision bodies can be used for bearing the movable virtual object so that the movable virtual object can move along any direction on the path-finding track. Further, a movable test virtual character can be created in the target virtual scene, and the test task is configured to the test virtual character, so that the test virtual character can move along the extending direction of the path-finding track according to the test task. When the test virtual character can traverse the path-finding track, a movable virtual object is created at the corresponding position of the collision body according to the virtual asset acquired in advance. That is, referring to fig. 14, a test task may be configured to a test virtual character, for example, including a character path corresponding to a track to be run by the test virtual character, and a corresponding action may be configured to the character, and during the running test, the running test process may be presented in real time using a display device, so that parameters of a scene window and corresponding parameters of a virtual camera in the scene, for example, parameters of a rotation angle, an inclination angle, a distance between the camera and the test virtual character, and the like, may be configured.

Further, virtual objects, such as interactable NPC roles, may be added to the target virtual scene, so as to increase the playability of the target virtual scene, for example, an area of a path corresponding to the track in the scene module may be determined, and further, a distribution density of the movable virtual objects created at the position corresponding to the collision body in each scene module may be determined according to the area of the path corresponding to the track in the scene module. For example, when the area of the corresponding path in the partial scene module is larger, a movable virtual object with a larger distribution density, such as NPC, may be configured in the path, for example, the path may correspond to a mart in a virtual scene, where a larger number of NPCs should be included.

It should be noted that, the method of the embodiments of the present application may be performed by a single device, for example, a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present application, and the devices may interact with each other to complete the methods.
